CMC Triggers has announced the release of the CMC Triggers Suppressor Optimized Enhanced Bolt Carrier Group for the new Hornady 6mm ARC.
CMC is the original manufacturer of the AR Drop-in Trigger Group since 2003. The new bolt carrier is designed for shooters who demand superior performance weapon components in the heart of their firearm, the company said in a press release.
The flared rear of the enhanced bolt carrier
is designed to reduce carrier tilt/cant during recoil and increasing
reliability by strategically relocating key bearing surfaces.
The CMC enhanced carrier has fewer points of contact resulting in
less friction area and the increase in mass ensures proper gas pressures and
increases dwell time, thus improving extraction while shooting suppressed or
short-barreled rifles (SBRs). Here are the specs:
- Case-hardened 8620 steel (complete care is taken during the heat treat process, so as to not harm the metal).
- 3 forward ports, enlarged to allow overpressure to escape.
- Optimized for suppressor use.
- Black Nitride Finish.
- 4130 Steel, attached with Grade 8 hardware, torqued and properly staked into a milled “valley” around a fully encased ejection port area, for added strength and rigidity.
- Hardened 4340 cam pin.
- Fully chamfered cam pin channel.
- Mil-Spec firing pin made of AISI 8740 steel, center-less ground and Hard Chrome coated.
The Bolt is “true” Mil-Spec dimension and external surfaces are CNC ground after heat treat for a precision fit, CMC said. The bolt is machined to the 6mm ARC (Advanced Rifle Cartridge) Hornady factory round spec. These bolts are held to the highest possible tolerance possible. Outside critical dimensions held to .0005”. The “trumpet” area behind the gas rings, where carbon normally collects, is precision CNC Ground after heat treatment, to ensure as smooth of an area as possible, easing clean up, and longevity.
Check these specs:
- 9310 Case Hardened Steel.
- All Bolt components Shot Peened & Black Nitride coated.
- 4340 Steel, Manganese Phosphate coated.
- Magnetic Particle Inspected (MPI) and High Pressure Tested (HPT).
- Black Nitride low friction coating.
- Mil-Spec Billet Extractor Spring & CRANE O-Ring Upgrade.
The New 6mm ARC (Advanced
Rifle Cartridge) from Hornady is a game-changer in the AR15 world, according to
the CMC release. Allowing AR15 configured rifles chambered in the 6ARC to reach
out to 1,000 Yards with ease.
